Abstract
A data storage device 12 includes a disk 14 having a surface zone 14a for storing data, and an access head 18 mounted on a slider 20 for writing data to and reading data from the data zone. The head 18 flies across the data zone 14a to access selected data tracks during spinning of the disk. And, the slider 20 seeks a predetermined shock buffer zone 30 atop the spinning disk, where critical data is not stored, during an idle mode for confining thereto any shock induced contact between the slider and disk surface.
Claims20
A data storage device 12 comprising:
- a disk 14 having an annular surface zone 14a extending radially between inner and outer boundaries 14b,c for storing data;
- means 16 for spinning said disk 14;
- an access head 18 mounted on a slider 20 for writing data to and reading data from said data zone 14a;
- means 22 for flying said head 18 across said data zone 14a;
- and
- means 28 for seeking said slider 20 to a predetermined shock buffer zone 30 atop said spinning disk during an idle mode when said data is neither written to nor read from said data zone 14a.
A method for enhancing data integrity stored in a data zone 14a of a spinning disk 14 accessible by a slider 20 mounted access head 18, comprising:
- flying said access head 18 across said data zone 14a to write data thereto and read data therefrom;
- and
- seeking said slider 20 to a predetermined shock buffer zone 30 atop said spinning disk 14 during an idle mode when said data is neither written to nor read from said data zone 14a.
